ROTARY MOTOR.

SPECIFICATION forming part of Letters Patent Noi 562,382, dated june 23, 1896. Application filed February 28, 1896. Serial No. 581,163. (No modeL) Patented in France August 17, 1894, No.240,'799.

Be it known that I, GEORGES FILTZ, a citizen of the Republic of France, residing at Paris, France, have made certain new and useful Improvements in Rotary Machines Used as Motors or as Pumps, (patented in France August 17 1894, No. 2e0,799,) of which the following is a specification.

This invention relates to a rotary machine which can be driven by all fluids and can be used as a motor or pump.

The following is a clear description of the machine, reference being made to accompanying drawings, in which Figure 1 is a vertical transverse section of the apparatus on the line no of Fig. 2. Fig. 2 is a vertical longitudinal section thereof; Fig. 3, a horizontal section on the linew at of Fig. 4 is a view of theinside of one of the bottoms of the cylinder on the line y z of Fig. 2. Fig. 5 is a lateral view in elevation of one of the ends of the cylinder. f Fig. 6 is a detailed View of the construction of. the paddles of the rotary piston.

The machine consists of a casing or cylinder A, carrying at its upper part the distribution-conduits and at its lower side a basepiece a, serving to support the machine. The

motive piston B, fixed upon an axle O, supported in the center of the ends D and D, closing the two extremities of the cylinder A, revolves freely in the cylinder.

The piston B consists of a cylindrical body of the same length as the casing A, deeply hollowed at both extremities, as will be clearly seen in Figs. 2 and 3, so as to form two recesses or chambers M M, separated by a thin partition or disk I), which divides the cylinder A in two equal parts and which connects the central socket b of the piston wedged upon the shaft 0 with the periphery b of the piston. The said'piston carries two transverse driving-paddles E E, placed at each side of the axle O and sliding freely in mortises cut longitudinally in the body of the piston, so that their rounded edges are guided for their entire length in similarshaped grooves e 6, made in the case b and the calender b of the piston. The ends D Dare also provided with interior cheeks cl, penetrating into the annular chamber of the piston 13, and

which end in a helicoidal surface or curvedshape plane 01, as clearly shown in Figs. 3 and 5; and these ends or plates are so located that the projecting parts of the cheeks are placed at a distance of one hundred and eighty degrees the one from the other and are in constant friction with the corresponding sur- 7 face of the disk or partition b of the piston, so that they form there a tight joint, which is shown in the drawings as being obtained by a spring-fitting F, fitted at the top of the check 01, Fig. 2. Under such conditions the distance between the curved planes d of the two ends D D is constant and corresponds exactly with the length of the paddles E E. It will be understood that during the rotations of the piston these paddles are constantly displaced by the friction of their extremity against the two planes which compel them to slide in thegrooves e e and to penetrate alternately into the two opposite chambers M M of the piston B, which they thus each di- 'vide in two parts, as clearly shown in Figs.

1 and 4. The result of these arrangements is that the chambers vary constantly during the rotation of the piston, as it is determined bythe distance between the disk cl of said piston and the parts of the corresponding plane I), which vary at each moment, which parts are comprised between the paddles or.

between the paddle and the stop f.

In this machine the inlet and outlet of steam occurs as follows: The ends D D are hollow and are divided intwo parts by a solid partition g, so that one of these parts, h, puts the inlet-pipe of the steam with the inletopening 76, while the other part, h, connects the out1et-opening Z with the pipe j, serving for the escape of the steam. Figs. 1 and 1 show the relative positions of the port-holes 7c and Z at each side of the fitting F, placed upon the projecting edge of the planes of the ends D D.

I have illustrated in the drawings a machine with reversing motion by means of a cock with a hollow seat N, which permits connection optionally of the conduits t' 3' either with the inlet or outlet devices for the steam, the inlet taking place through the open extremity belonging on one side to the screwed stopper Q and on the other side to a socket B, through which the shaft 0 passes. This arrangement prevents all leaking without the need of using a stuffing-box.

Finally, in order to assure the tightness of the joints against the extremities of the paddles E and the planes d of the ends D D, I

preferably construct the paddles of two pieces, between which a spring is inserted,

as shown clearly in Fig. 6,

The operation is as follows: Supposing the paddles in the position shown in Fig. 4 it will be seen that this side of the piston is divided in three chambers as follows: One

chamber m,in which the admission is effected, and which is limited to one side by the edge F and on the other side by the paddle E;

one chamber m, into which the steam passes, which is limited by the two paddles E E,

and, finally, one chamber m connected with' the outlet and limited by the paddle E and the edge F. It will be seen that as a result of the rotary motion of the piston in the direction shown by the arrows the size of the chamber m will increase gradually while the steam penetrates therein, by pressing the paddle E, and that such will be the case until the paddle E has passed by the edge F and the port-hole K, when it will become motive at its turn. During that time the steam which had entered previously and which is contained in the chamber m, limited by the two paddles, will be displaced in a circle while expanding in a certain proportion until the paddle E has passed by the port-hole Z, and at that moment the steam will pass in the escapement-chamber. Said paddle will finally pass by the edge F, then the port-hole K, and will assume the position shown by the letter E, commencing a new cycle of operation again. But similar operations will at the same time take place in the opposite part M of the piston, and as the projecting edge F atthat side is at a distance of one hundred and eighty degrees of the position shown in Fig. 4, the motive effect is produced at alternate periods corresponding to one half-revolution upon the two surfaces of the piston, which thus transmits constant efforts upon the ,axle G, assuring the regularity of the operation. On the other hand, the interposition of an intermediate chamber m between the inlet-chamber m and the outlet-chamber m in which intermediate chamber the admitted steam will be displaced in a circle before escaping, will greatly reduce the leaks around the periphery of the paddles.

I have hitherto spoken of the steam as motive power; yet it is obvious that the workin g of the machine will be the same no matter what may be the nature of the fluid, air or gas used.

It will be understood also that in order to use the apparatus as a pump it will be sufficient to drive the shaft 0 by means of a motor and to connect the inlet and outlet openings with the liquid, it being well understood that the dimensions of the port-holes and of the interior conduits of the machine must be constructed so that the liquid can run out.

I do not limit myself to the forms and arrangements shown in the drawings, but reserve the right to use the same for all purposes for which the apparatus can be used.

I claim--- 1. In combination, the casing, the cylindrical piston rotating therein and having chambered ends, the hollow helicoidal cheeks projecting within the chambered ends and formingpart of the casing, the sliding paddles carried by the piston, the inlet and outlet ports in the helicoidal-cheek faces, the fluid passage-ways leading to said hollow cheeks, and the reversing-valve controlling said passage-ways substantially as described.

2. In combination, the casing, the cylindrical piston having chambered ends, the helicoidal cheeks projecting within said ends, and the paddles sliding longitudinally of said piston, each paddle being formed of two in terlockin g parts with means'for exerting pres sure tending to separate said parts, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of the two subscribing witnesses.
